Apparatus and Method for Supporting Burst Arrival Time Reference Clock Based on Time-Sensitive Communication Assistance Information in Wireless Communication Network

2. The method of claim 1, wherein information on the burst arrival time mapped to the 5G clock is included in time-sensitive communication assistant information (TSCAI) provided to a node of an access network.

3. The method of claim 2, wherein the TSCAI is transmitted based on a protocol data unit (PDU) session modification procedure.

5. The method of claim 2, wherein the report message further includes a frequency offset between the 5GS time and the TSN time and the frequency offset is used for mapping of a period from the TSN clock to the 5G clock in the SMF.

6. The method of claim 5, wherein the TSCAI includes information on the period mapped to the 5G clock.

8. The apparatus of claim 7, wherein information on the burst arrival time mapped to the 5G clock is included in time-sensitive communication assistant information (TSCAI) provided to a node of an access network.

9. The apparatus of claim 8, wherein the TSCAI is transmitted based on a protocol data unit (PDU) session modification procedure.

11. The apparatus of claim 8, wherein the report message further includes a frequency offset between the 5GS time and the frequency offset is used for a mapping of a period from the TSN clock to the 5G clock in the SMF.

12. The apparatus of claim 11, wherein the TSCAI includes information on the period mapped to the 5G clock.
